binaries that failed to run for lack of the shared library.

* gnu/packages/acl.scm (acl): Disable tests.  Remove customized
  'check' phase that ran tests and ignored errors.  Remove 'perl' as
  input, needed only for tests.  Replace 'install' phase with one that
  includes 'install-lib' target.

was handled by an expression common to several packages.

* gnu/packages/cmake.scm (cmake): Likewise.
